现在是点击加载更多的按钮后开启一个线程执行取回数据就是代码中的uses，进行setAdapter，每次点击按钮后ListView都是刷新，怎么能实现加载更多地功能呢

部分代码如下：
线程中的Handler:
LinkedList<User> users = jsonUtils.parseUserFromJson(DataContent);
myadapter.setUser(users);
myadapter.notifyDataSetChanged();
lv.setAdapter(myadapter);

//////////////////////////////////////////
以下是重写的adapter
class ListViewAdapter extends BaseAdapter{

LayoutInflater inflater;

LinkedList<User> users;

public ListViewAdapter(Context context){
inflater = LayoutInflater.from(context);
//this.users =users;
}
public void setUser(LinkedList<User> users)
{
this.users =users;
}
@Override
public int getCount() {
// TODO Auto-generated method stub
return users.size();
}

@Override
public Object getItem(int arg0) {
// TODO Auto-generated method stub
return users.get(arg0);
}

@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
View view = inflater.inflate(R.layout.list_item, null);
User user = (User) this.getItem(position);

TextView user_title = (TextView) view.findViewById(R.id.title);

user_title.setText("Title-->"+URLDecoder.decode(user.getTitle()));

return view;
}
}
